– Under the product name Quantum Colors brings Osram Opto Semiconductors, a new Quantum Dot technology to market that dispenses with cadmium, covering DCI-P3 to 100% – and even half as expensive as methods of competition.

The coming year will bring a whole lot more at the display technologies of contrast, color and color fastness and the black levels Wide Color Gamut is important -.. in the B2B market and B2C applications, the way there are many – OLED, for example, one of them
On the other fork in the road -. in the LCD technologies, which can not do without a LED backlighting unlike OLED -. Things are happening in the market for quantum dots What at UHD TVs and computer monitors for professionals and prosumers also could express themselves in a price decline
At QD and the market to QD is fighting for market share -. and also industry-internally and publicly grappled over whether to continue to rely on such technologies should that contain cadmium.
Now, Osram Opto Semiconductors brings the new conversion technology Quantum Colors on the market. Their main characteristics: a significantly better color gamut and according to the manufacturer significant cost savings compared to traditional Quantum Dot Sheets technology and cadmium-free

The first customer projects; the use of Osram technology to the mass market for LED backlighting is planned to the end of 2016.
Quantum Colors based on a green Quantum converter which is combined with red phosphorus on a blue chip. The technology has been partially developed in the EU or BMBF funding projects SSL4EU and Hi-Q LED and involved no cadmium. This results in numerous advantages over Quantum Dot Sheets, the usual for maximum color claims in TV backlighting technology: In the color gamut Quantum Color is superior because through a narrow spectral half width of 30 nm in the green color space standards as DCI-P3 may be covered at 100% and REC2020 to more than 80%.
Also requires the Osram technology no additional adjustments to the system or other components. So manufacturing processes and the entire system can be simplified.
The cost can be compared to Quantum Dot Sheet solutions that are based on a few nanometers large semiconductor particles, halved. “An example illustrates the large savings for the customer,” says Peter Lenz, Product Marketing LED at Osram Opto Semiconductors. “With a 55″ TV with Ultra HD 100% DCI cover can be realized in our Quantum Color technology with complete bulbs cost of only 55 Euro based. In previous solutions, however, would alone already incurred the costs of the double quantum dot Sheet. “
Another benefit is that over the life of constant constant color. In Quantum Dot Sheets these changed over time, according to Osram bluish. When it comes to life Quantum Color LED should reach at least 30,000 hours; first tests are already showing positive results.
It is possible that in addition to TV set manufacturers also AiO vendors like Apple (Retina iMac from 2016 or 2017) and Monitor forging as Eizo pleased with a backlighting could find technology that becoming the more important Color Space DCI-P3 met too loose 100% – and which is yet to implement better cost
The Quantum Dot providers falling achievable prices could be a consequence.. Also OLEDs are medium to further falling prices hit the market.
